About

Nomos does license identification using short phrases (regular expressions) and heuristics (e.g. phrase must be found in (or out of) proximity to another phrase or phrases).

Nomos may also identify a "style" type of license if it has similarities with a known license type.

The signatures which uniquely identify a license are stored in STRINGS.in file.

If you wish to contribute to Nomos, please read How to add a new license signature.

Debugging

Activating the defines of PROC_TRACE and/or DOCTOR_DEBUG (see line 31 of file parse.c). Nomos generates lot of tracing information that is really helpful to debug it.

PROC_TRACE will show you, for example, which regex's were tried and which are successful. To see the successful matches, grep the output file for "addRef".

DOCTOR_DEBUG will show you the before and after versions of the buffer to be processed. Look in the output file or ----- [Dr-BEFORE:] ----- and +++++ [Dr-AFTER] +++:
